How to Install Apache Spark: Step-by-Step Guide

Apache Spark is a powerful open-source unified analytics engine designed for large-scale data processing. It is widely used for big data and machine learning applications. This guide will walk you through the process of installing Apache Spark on your local machine or a server.

Prerequisites

Before you begin, ensure you have the following prerequisites:

• Java Development Kit (JDK) 8 or later. How to Install Java.
• Scala installed on your system. How to Install Scala.
• Hadoop (optional for standalone setup).

Downloading Apache Spark

Visit the Apache Spark download page and download the latest version of Spark. Choose a pre-built package for Hadoop as needed.

$ wget http://apache.mirrors.tds.net/spark/spark-x.y.z/spark-x.y.z-bin-hadoopx.y.tgz

Extracting and Setting Up Environment Variables

Extract the downloaded Spark archive and set up environment variables:

$ tar -xvzf spark-x.y.z-bin-hadoopx.y.tgz
$ export SPARK_HOME=/path/to/spark
$ export PATH=$SPARK_HOME/bin:$PATH

Add these environment variables to your .bashrc or .zshrc file to make them permanent.

Running Spark

Start the Spark shell to verify your installation:

$ spark-shell

If Spark starts without any errors, your installation is successful. You can also run spark-submit for running applications:

$ spark-submit --class <class-name> <jars> <app-args>

Troubleshooting

If you encounter issues during installation, consider the following troubleshooting tips:

• JAVA_HOME not set: Ensure JAVA_HOME points to your JDK installation.
• Scala version mismatch: Ensure compatibility between Spark and Scala versions.
• Firewall issues: Ensure ports required by Spark are open if running on a server.

Summary Checklist

• Ensure Java and Scala are installed.
• Download and extract Spark.
• Set up environment variables correctly.
• Run spark-shell to verify installation.
